Very rarely which is a surprise as the hangers that they are on instantly gives the game away , i might get a knowing smile, apart from once last year i went to try a blouse on and the assistant at the changing rooms said "are you taking that in for your wife " so i said no, so she asked again is it for someone else , i said no again it is for me , so she said is it for fancy dress or something , i just thought how dumb can you get and just replied ,yeah something like that , when i came out my wife was laughing her head off because she had seen the whole thing happen .
